Makranczy, Gy.: Systematics and phylogenetic relationships of the genera in the Carpelimus group (Coleoptera: Staphylinidae: Oxytelinae)

bears no tubercles. - Male terminalia. Sternum IX [51 and 52] absent. - Male genitalia. Aedeagus median lobe [53] bulb-like, internal sclerites [54] present, symmetrical/paired. Apical opening [55] simplified, truncated. Median face membranous [56], without apicomedial hook [57]. Parameres [58] not wrapping, sometimes with extra lobe [59], often with membranous region [60], with one seta [61] each. Without visible pump and flagellum [62]. - Female terminalia. Female genital appendages [63] are lost. Sclerites (possible remnant of sternum X) [64] appear as small ring. - Female genitalia. Spermatheca [65] sclerotized. Receptacle [66] divided, not associated with visible or invisible [67] spermathecal gland, tubular portion [68] not penetrating distal bulb, umbilicus [69] absent. Sclerotized "tube" [70] sometimes can be found. Diversity and distribution - Carpelimus is a worldwide genus with a vast number of species (currently about 400 named and valid) and relatively little diversity (for the most part) and ubiquitous life habits. They characteristically live near slower running waters or muddy places, near ponds. Thinodromus KRAATZ, 1857 Thinodromus KRAATZ, 1857 (type species: Trogophloeus dilatants ERICHSON, 1839) Amisammus DES GOZIS, 1886 (type species: Carpelimus arcuatus STEPHENS, 1834) Warburtonia OKE, 1933 (type species: Warburtonia inflatipes OKE, 1933) Paracarpalimus SCHEERPELTZ, 1937 (type species: Homalotrichus luteipes SOLIER, 1849) Apocellagria CAMERON, 1920, syn. n. (type species: Apocellagria indica CAMERON, 1920) Carpaliaceus GlLDENKOV, 2000 (type species: Carpaliaceus thoracicus GlLDENKOV, 2000) Description - Medium to large sized (1.9-7.8 mm), usually dark brown to almost black, but some medium to yellowish brown (even if fully coloured). Body covered with sometimes rather long pubescence. Most species have a broad, transverse groove before the basal edge of pronotum. Elytra parallel-sided, sometimes reduced (wingless species), temples developed, abdomen broadest at (or around) the 6th segment. The difference in the formation of sternite VIII (not broadly rounded) helps recognizing the males; also, in several species groups the antennái segments of the male are more elongated than that of the female - this feature is, of course, easier to observe in those species where the antennái segments are otherwise longer than broad. - Head. Clypeus [1] well developed, epistoma! sulcus [2] present. Eyes [3] not extending to the ventral portion of the head. Gular sulci [4] confluent at least anteriorly. Head [5] without midline keel. The mola [6] on the mandibles separated, well developed. Labrum [7] divided, transverse [8]. Setation behind front of labrum [9] in middle much smaller, irregular or missing. Dorsal seta [10] on epipharynx absent. Hypopharynx [11] divided or undivided, without coriaceous field [12] on ventral side. Lateral row of bulbous setae [13] present or absent. Front of hypopharynx [14] entirely or not entirely covered with setae, no setae [15] on mid-line. Median sclerotized plate of hologlossa [16] anteriorly enlarged into a plate with central stick either or not continuing till end. Last palpomere of maxillary palp [17] cither bulbous basally or reduced to a stick, digitiform sensillae [18] pre*--" ;

f

. on last palpomere, fused to the apex or middle of penultimate, or completely missing; if n;estt..t, nrfanged [19] in parallel fashion. Apex of penultimate segment of labial palp [20] hairy or lot. Antennae Til] straight and [22] moderately elongated. -Thorax. Prosternai process [23] poin'.ed, scutellum '24j without pubescence, hypomera [25] not exposing protrochantins. - Legs. Tibia [26] with or without m'd-tibial spur(s) but [27] without spines or rows
